Ounces to Cups All-Purpose Flour Cooking Size Chart
This chart converts all-purpose flour between ounces and cups, covering 10 measurements from ounces 0.6 up to ounces 13.2. Because all-purpose flour has a specific density that differs from other ingredients, these conversions apply only to all-purpose flour — do not use them for other ingredients.
In baking and cooking, precision matters. A recipe calling for ounces 0.6 of all-purpose flour needs exactly cups 1/8 — using a conversion for a different ingredient could throw off the balance of your recipe. Our chart accounts for the actual weight-to-volume ratio of all-purpose flour.
Two of the most common conversions on this page: ounces 1.5 of all-purpose flour is cups 1/3, and ounces 6.6 is cups 1.5.

How to Measure Your Ingredients Size
For dry ingredients, spoon the ingredient into the measuring cup and level off with a straight edge — never scoop directly from the bag, as this packs the ingredient and adds up to 20% extra weight. For liquids, use a liquid measuring cup (with a pour spout) and read at eye level on a flat surface. A digital kitchen scale is the most accurate option and eliminates the need for volume conversions altogether.
Tips for Converting All-Purpose Flour Cooking Sizes
Humidity, packing density, and grain size all affect how much of a dry ingredient fits in a cup. Two people measuring '1 cup of flour' can end up with weights differing by 30 grams.
When a recipe gives both weight and volume, always prefer the weight measurement — it is what the recipe developer used.
Weight-based measurements (grams, ounces) are more accurate than volume measurements (cups, tablespoons) for baking. Professional bakers almost always weigh ingredients.
Quick Reference

Frequently Asked Questions
- How do I convert all-purpose flour from ounces to cups?
- Use our all-purpose flour conversion chart above. For example, ounces 3.3 of all-purpose flour equals cups 3/4. The chart covers 10 measurements so you can find the exact conversion you need.
- Does all-purpose flour weigh the same as other ingredients per cup?
- No. Each ingredient has a different density, so 1 cup of all-purpose flour weighs a different amount than 1 cup of flour, sugar, or any other ingredient. That is why ingredient-specific conversion charts like this one exist — using a generic converter will give inaccurate results.
- Should I measure all-purpose flour by weight or volume?
- Weight (grams or ounces) is more accurate for baking because volume measurements like cups can vary by up to 20% depending on how the ingredient is scooped and packed. If your recipe gives both, always prefer the weight measurement. A digital kitchen scale is the most reliable tool.
- What is the smallest all-purpose flour conversion in this chart?
- The smallest measurement in our chart is ounces 0.6 of all-purpose flour, which equals cups 1/8.
- What is the largest all-purpose flour conversion available?
- The largest measurement covered is ounces 13.2 of all-purpose flour, which converts to cups 3. If you need a larger quantity, multiply the appropriate row from our chart.
- How do I measure all-purpose flour accurately for baking?
- For cups, use the spoon-and-level method: spoon all-purpose flour into the measuring cup, then sweep a straight edge across the top to level it off. Never scoop directly from the container — this packs the ingredient and gives you more than the recipe intended. For grams or ounces, use a digital scale set to zero (tared) with your bowl on it.
- Can I use this chart for all-purpose flour in savoury recipes too?
- Yes. The weight-to-volume ratio of all-purpose flour is the same regardless of whether you are baking or cooking a savoury dish. These conversions apply to any recipe that calls for all-purpose flour.
